Ashcroft 94243XLL Pressure Gauge 0-5000 Psi 3.5in Dial

Product Description

The ASHCROFT 94243XLL is an industrial-grade analog pressure gauge designed for high-pressure monitoring applications up to 5000 psi. It features a 3.5-inch dial with a 1/4-inch MNPT lower-mount connection, making it straightforward to install on threaded ports and manifolds. The wetted parts and Bourdon tube are constructed from 316 stainless steel, and the case is 304/316 stainless steel, providing corrosion resistance in demanding service environments. Accuracy is rated at 1 percent of scale across the full 0 to 5000 psi range. The gauge is dry (no liquid fill) and uses a polycarbonate lens. Licensed HVAC technicians, plumbers, pipefitters, and industrial service professionals install this type of gauge.

This gauge suits industrial, commercial, and mechanical system applications where reliable pressure indication is required at elevated pressures. The lower-mount MNPT connection fits standard threaded ports on piping, test manifolds, pumps, compressors, and pressure vessels. The stainless steel wetted parts make it appropriate for use with water, air, oil, and many compatible process fluids. The dry-fill configuration keeps the dial readable without fluid cloudiness over time.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge suitable for threaded piping systems, compressors, pumps, and pressure vessels requiring a 1/4-inch MNPT lower-mount connection and a 0 to 5000 psi range.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified industrial service technicians. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant or PTFE tape to the MNPT threads per applicable installation codes; do not over-torque the connection. Verify the process fluid is compatible with stainless steel wetted parts before placing the gauge in service.
